ccamrobertson··on Show HN: Burner – A low cost wallet to gift crypto
We considered this, but thus far I’ve only had someone ask me if I’m a Burning Man participant after seeing the logo.
ccamrobertson··on Show HN: Burner – A low cost wallet to gift crypto
Not opposed to doing a Solana variant!
ccamrobertson··on Show HN: Burner – A low cost wallet to gift crypto
You can just gift ETH. And good news, as a stablecoin backed by dollars USD II is pegged to the dollar so no “pumping” or “dumping”.
ccamrobertson··on Show HN: Burner – A low cost wallet to gift crypto
There is a massive trillion dollar market around gifting dollars on gift cards today, but you can typically only use them on Visa and Mastercard networks. We think gifting stablecoins is a better way to do that.
ccamrobertson··on Show HN: Burner – A low cost wallet to gift crypto
The same reason one would use any other stablecoin like USDC, you want to send dollars to someone.

The added benefit is that you don’t need to be worried about sending ETH as well to use USD II. Put another way, if I gift you a Ledger with USDC today, you as a possible crypto newbie need to work out how to get ETH to move that USDC.

ccamrobertson··on Show HN: Burner – A low cost wallet to gift crypto
You can! We just don’t feature it in the gift card “optimized” mode since we do not subsidize the gas costs for existing stablecoins.

Hmm, thanks for the report. I use uBlock origin as well but I might have it in some more permissive state...
ccamrobertson··on Launch HN: Deepsilicon (YC S24) – Software and hardware for ternary transformers
Congrats, always cool to see YC founders working on silicon!
ccamrobertson··on Another Silicon Valley institution died spring of 2019: Halted/HSC
I preferred Weird Stuff, but we still used Halted for same-day popcorn supplies we needed in 2013-2014. The day Weird Stuff closed was the day "old" Silicon Valley died for me.

Despite not being a surplus store, I would add Frys to the list of culturally relevant Silicon Valley electronics stores now lost to time. It was worth taking a day to visit all the SV locations to compare the hokey aesthetic choices (I was closest to the Wild West Palo Alto branch, but I think the Campbell Pyramid was my favorite).

Odd commentary given that returns of Bitcoin are phenomenal if you bought in most periods since 2018 except for the previous all time high.

> Why would anyone want to buy Bitcoin or own it unless they are hiding money for criminal purposes or dealing in the dark web.

Take a look into distributed ledger technology; it turns out that everyone can see where Bitcoin transactions are coming from and going to unlike, say, dollars where international banks regularly launder billions (and receive only mild penalties for doing so).

ccamrobertson··on A Historical Tour of Silicon Valley (2010)
We rented the Byte Shop building as an office from 2013-2016.

After the Byte Shop left the space, it became what Steve Jobs affectionately referred to as an "adult bookstore" for the next thirty or so years until we leased it for a massive discount; the landlords had forgotten the history and could not fathom why anyone would want the space given its most recent sordid occupant.

We kept an Apple // in the window and even hosted an open house. Sadly I suspect its days are numbered as nearly all the buildings around it have been redeveloped (including the infamous Frankie, Johnnie and Luigi Too restaurant where Jobs bribed engineers with pineapple pizza).

ccamrobertson··on Beeper Mini users find Macs banned from iMessage network
> I’m sure the founder realized early on that the prospects of this becoming a valuable company on its own merits were slim

If you actually knew Eric and the history of Beeper you would understand how hilariously false, absurd and revisionist such a statement is. Eric only started Beeper after validating massive interest from Hacker News for a paid app that would unify disparate communication channels.

ccamrobertson··on The feds' vehicle 'kill switch' mandate is a gross violation of privacy
No, to castigate the effort is precisely helpful in a case where it results in a gross violation of privacy — potentially even impact constitutional rights directly.

The entire point of this article is that other news sources and “fact checkers” are being obtuse (or simply lying) to deny the fact that a kill switch has been called for.

This is typical Overton window bullshit; “no, no, that’s not what they want to do,” and of course five years later it’s completely apparent that indeed we have implicit (and probably even explicit) kill switches in cars.

ccamrobertson··on Apple plans to equip MacBooks with in-house cellular modems
MacRumors should at least link to their own article from 2011 talking about the actual MacBook Pro prototype that was discovered in 2011 ("Tyco"): https://www.macrumors.com/2011/08/14/photos-of-a-prototype-m...
ccamrobertson··on Apple finally put USB-C in new iPhone, but limited to 23-year-old USB 2.0 speeds
I do because I despise the idea of iCloud, but I’m also completely happy to pay more for USB 3.0. It’s like the new MacBook Pros — ample ports (again), which for my uses are worth paying for.
ccamrobertson··on The Fill and Flush deplaning method
I love this because it's exactly the thing that an enraged engineer who is stuck in the last row waiting to get off a plane would create -- just a little naive given airline incentives, couples, families and the limits of human patience :)

I would much rather if all planes had a second staircase at the back, jet bridges aren't needed. That, or let people check luggage for free again so they don't need to manhandle carry-ons.

My guess is that airports also prefer a slower release of passengers -- it means customs lines and bathrooms aren't immediately saturated.

ccamrobertson··on People over-emphasize the recycling aspect of "reduce, reuse, recycle"
“ the growing waste production catastrophe.”

Or maybe waste production isn’t a “catastrophe” and reuse should be dependent on economic rationale rather than virtue signaling.

ccamrobertson··on Show HN: 77 Year old launches SaaS platform today. Seeks feedback
I would love this for low cost land plots (sub $50k). I see a lot of people listing land like this on Facebook Marketplace; feels like this platform could be ideal for that.
ccamrobertson··on Automakers are starting to admit that drivers hate touchscreens
We just bought a 2023 6-speed Crosstrek and it’s amazing. Also, fewer (color) screens because it’s practically the base.

Sadly the last year one can get it as a manual.

ccamrobertson··on Launch HN: Electric Air (YC W23) – Heat pump sold directly to homeowners
Congratulations on the launch!

Would it be possible to combine both a ducted system with a mini-split style head unit? Our ducting is old, undersized and with poorly located returns.

ccamrobertson··on ‘Compostable’ plastics no longer able to be composted in Boulder
The paper leaf bag ban is the worst part. Not looking forward to fall 2023.
ccamrobertson··on The 20-Somethings Fueling a Stick-Shift Renaissance
For a new car with a warranty, that makes sense. For the anywho who works on their own car, automatics are an incredible pain.

Most failure modes are catastrophic and require a full rebuild as all components are integrated. Coolant lines that run into the engine bay are a hazard when doing common work like replacing radiators. They’re typically heavier.

High wear components in manuals like clutches, pilot bearings and master/slave cylinders are straightforward to replace.

Clutchless shifting with a DSG or tiptronic is a far cry from meshing synchros. Smoother, yes, but sportier is up to the eye of the beholder here.

ccamrobertson··on Private Prisons Are Behind the Push for Homeless Criminalization
Which private prison (or adjacent) company has 8vc invested in?
ccamrobertson··on Show HN: Celody – A Music Network State
> What a wild and weird concept. I'd love to see more art projects like this.

Yes. This is a fascinating experiment; I would love to see the code to understand if it approaches a true "decentralized autonomous organization".

ccamrobertson··on Show HN: The Bitcoin Note – Secure, Self-Custodial Bitcoin Wallets in Cash Form
Yes, that makes more sense, I was mischaracterizing it. 1-of-1 is more appropriate (although the notion of a 1-of-1 multisig is a little odd at face value until one digs in).
ccamrobertson··on Show HN: The Bitcoin Note – Secure, Self-Custodial Bitcoin Wallets in Cash Form
Thank you, always great to get praise from another hardware founder :)
ccamrobertson··on Show HN: The Bitcoin Note – Secure, Self-Custodial Bitcoin Wallets in Cash Form
We used Greco-Roman god statues -- Apollo, Venus, Minerva and Neptune (some of the model statues were Greek, others Roman). We chose aspiration mythical figures to point to some deeper Bitcoin lore. I will hold off with details and let our note designer tease out the meaning there.

Hmm...where? Given all the last minute touch ups to the site I wouldn't be surprised...

ccamrobertson··on Show HN: The Bitcoin Note – Secure, Self-Custodial Bitcoin Wallets in Cash Form
We've dabbled with the idea of making a Kong note using the same tech we're applying for the Bitcoin Note, but the requirement for a large fixed run of notes and the niche appeal of Kong makes this tricky.

While Kong Cash notes are gorgeous, there are couple additional reasons we likely won't ever make another cryptocash note like that again: resilience over time in your wallet and the flex-PCBA manufacturing process rather than a print process (the former being far more complex with limited print detail possible). That said, we believe that we are likely still the only mass production run of flex PCBs that incorporated a full-color digital print :)

It's indeed a tricky problem --

> If the issuer can always sign unilaterally

Based on the construction of the multisig we never have custody over the Bitcion, even if we store the encrypted key (we don't).

> If the funds can be lost through loss of user keys, then this offers little practical advantage over bill-less bitcoin

There are several; easy key diversification across multiple wallets. Easy offline storage away from connected devices. Easy onboarding.

It would be possible to backup the user keys on the notes independent of the note, we just believe that having them function more like cash guides the user to make choices where they are far less likely to lose them -- e.g. storing in a fireproof safe, safety deposit box, etc.

ccamrobertson··on Show HN: The Bitcoin Note – Secure, Self-Custodial Bitcoin Wallets in Cash Form
Depending on where in the lifecycle the note is, it's either a 2-of-2 multisig transaction or 1-of-2 multisig transaction, using only the user key in the latter case.
